Let´s follow the 27th ACM User Interface Software and Technology Symposium


The ACM Symposium on User Interface Software and Technology (UIST) is the premier forum for innovations in human-computer interfaces.

Sponsored by ACM special interest groups on computer-human interaction (SIGCHI) and computer graphics (SIGGRAPH), UIST brings together people from diverse areas including graphical & web user interfaces, tangible & ubiquitous computing, virtual & augmented reality, multimedia, new input & output devices, and CSCW.

The intimate size and intensive program made UIST an ideal opportunity to exchange research results and ideas.


The closing keynote is from Bret Victor. He was talking about the “Humane Representation of Thought: A Trail Map for the 21st Century.

Best Paper: Coordinated 3D Interaction in Tablet- and HMD-Based Hybrid Virtual Environments by Jia Wang & Robert Lindemann (Worcester Polytechnic Institute)

Our Ph.D. Candidate Steve Erik Funke joined the symposium that last for two days (Oct 4-5). The ACM Symposium on Spatial User Interaction (SUI) was the second international symposium. It is an unique opportunity for industrial and academic researchers to exchange about the state-of-the-art spatial and 3D interaction research. This considersboth spatial input and output, with an emphasis on the issues around interaction between humans and systems.

We focused on the user interface challenges that appear when users interact in the space where the flat, two-dimensional, digital world meets the volumetric, physical, three-dimensional (3D) space we live in. We had an intensive exchange with industrial and academic researchers working in the area of spatial user interaction.

The keynote was given by Keynote by Prof. Ken Perlin, NYU Media Research Lab.
The second Keynote by Prof. Mark Bolas, ICT, LA followed immediately by ACM UIST 2014.

The sponsors were ACM, ACM SIGGRAPH, SIGCHI and the Interaction Design Foundation.


Cyberworlds 2014

Group Picture CyberWorlds 2014

The Cyberworlds 2014 conference was held in Santander, Spain on October 6th to 8th.
Our collegiate Vincent attended and held presented his paper “Exploring Stereoscopic Multi-User Interaction with Individual Views”. The conference focused on cyberworlds and all related issues, including (but not limited to) computer graphics, shape modeling, user interfaces, virtual worlds, multimodal interaction and rendering, computer vision for augmented and mixed reality, multiplayer online games, social and affective computing, and cognitive informatics.

There were two invited speakers, Prof. Tomoyuki Nishita (University of Tokyo & Hiroshima Shudo University, JAPAN) with his talk “Shading Models for Extended/Environmental Light Sources” and Prof. Jian Jun Zhang (National Center for Computer Animation & Bournemouth University, UK) with “Virtual Human Characters and their Roles in Scientific Research”.

Both talks and the papers presented by the other scientists were very interesting and relevant to both CrossWorlds and other projects at the university.


EASST’14 – Talk on Robots in Elder Care

CrossWorlds assistant researcher Andreas Bischof has been attending EASST’14, europe’s most important conference on science and technlogy studies (STS).

The European Association for the Study of Science and Technology (EASST) has – like the field itself – geographical centres of gravitation in Britain, the Netherlands and Scandinavia. The organisation seeks to overcome this historic bias by allocating its bi-anual meetings in south and east european countries. The 2014 conference took place in Torun / Poland, Nicolaus Copernicus’ birth place! (Which is more than funny since Copernicus is the title hero of a very important study that kind of founded science and technology research, Thomas Kuhns »Copernican Revolution«.

Andreas’ talk was part of the panel »Governing Health Care Technologies«. Demographic ageing is widely seen as a “grand challenge”, and policy makers, industry, academic researchers, health care providers, and lobby groups have identified research and innovation as a promising response. In this context Andreas’ talk »Two Ways of Co-Constructing the User in Social Robotics« contributed to the discussion of practices of user-producer interactions in social robotics projects for elderly.

In particular he compared two projects implementing assistive robots in elder care in west european country. The question was how these projects integrated the elderly in the research & development of their robots. Crucial therefore are obviously user tests and the function of the thereby gathered data in the research process. The empirical research in the projects shows that institutional and political implications of the research shape the image of the user in such projects far more than actual user needs. Please have a look at the slides for details. For a more detailed insight see the German blog post from Andreas on his personal blog.


Exhibition MS Wissenschaft closes with 90.000 visitors

Exhibitionship MS Wissenschaft @Linz,Austria

MS Wissenschaft @Linz,Austria

September 28th the exhibition “Digital Unterwegs” on the ship MS Wissenschaft finally came to an end. In total it had 90.000 visitors, among them 480 school classes. The ship stopped in 38 german and austrian cities.

CrossWorlds researchers Kalja Kanellopoulos and Michael Storz contributed a multitouch table with applications for up to six players. The support staff reported us that the table was one of the most loved and most used exhibits in the exhibition. They also stated that the exhibit fostered interaction between people who didn’t know each other before and that despite its heavy usage the exhibit was still one of the easiest to maintain. On two of the last stops in Deggendorf and Regensburg we were able to conduct a user study, which will give us further insights into the mechanics and courses of action of playful tabletop collaboration.

Despite the fact, that we are still working on the detailled results of our study, it became clear, that this project was a great success and all the hard work and support for this exhibition was worthwhile.

The table is now in refurnishment and will be presented on November 17th at the Demosession at the ACM ITS conference in Dresden.


We like to move it, move it ;-)

After a week of the usual troubles while working in a half-way boxed-up office-space, the CrossWorlds Team finally is moving into their new habitat, half a World away aCross the street. If you want to find us, remember to look into the A-Wing of Reichenhainer Str. 70, Rooms 312 through 317.


Munich – Mensch und Computer 2014

As every year the biggest HCI conference in Germany the Mensch und Computer is a great opportunity to present our work and get into discussion with researchers from various fields. This years Mensch und Computer took place from 31st August to 3rd Semptember in Munich.

Fellow Michael Storz attended the doctoral symposium where he presented the current state of his thesis. A big thanks goes to the organizers professors Herrmann and Leimeister. Furthermore fellow Michael Heidt and research student Linda Pfeiffer contributed to the conference demo session.

For us this years highlight on MuC was Arne Bergers contribution “Personal Spacer” to the “Visionen” contest. A video featuring a provocative vision of the technology use in 2026. You can watch it here. (sorry, german only)

The first ‘Crossie’ defended his PHD thesis!

2014-07-17 12.06.32It happened! The first one of our Crossworlds colleagues, Daniel Pietschmann, has successfully defended his PhD thesis on July 17th. His dissertation is titled ‘Spatial Mapping in virtuellen Umgebungen: Der Einfluss von Stereoskopie und Natural Mapping auf die User Experience’ (Spatial Mapping in virtual environments: the influence of stereoscopy and natural mapping on the user experience). Daniel, the team congratulates you and your dedication to science and we hope to join you in the ranks of PhD, soon. 😀


Thank you for a great conference!

This monday and tuesday, many months of preparation finally culminated in having our CrossWorlds 2014 conference on Theory, Development, & Evaluation of Social Technology at Chemnitz University. On these two days, over 60 participants enjoyed interesting talks on interdisciplinary topics concerning the boundaries of virtual and real social worlds and also shared engaging discussions with each other – both at the conference venue and at the social evening on monday.

On behalf of the whole CrossWorlds team, we thank all the presenters and participants for making our conference a huge success. We hope, you had a great time in Chemnitz and enjoyed the conference as much as we did. We’re already looking forward for our next conference in 2016.

Now, after the conference, we are especially interested in your feedback and comments. We will also post pictures and presentation slides in the coming days. So please, check back, soon.

Your CrossWorlds team

Dagstuhl 2014

Quis, quid, quando, ubi, cur, quem ad modum, quibus adminiculis.

dagstuhl participantsNumerous participants of German Research Training Groups (RTG) met each other at the 8th Joint Workshop. The network meeting, funded by the German Research Foundation, took place on June
15 – 18 at Schloss Dagstuhl – Leibniz Center for Informatics.

To contribute to the chief task of Schloss Dagstuhl and the desiderata of computer science the RTGs emphasized “Interdisciplinary scientific working principles” which not only influence the attractor space of diverse computer scientific approaches and concepts, but also change the structure, formats and methods of computer science research programs, the academic conversion of related curricula, and the transfer-processes between theory and practice.

Student talks, cross-thematic seminars, student-professor and invited talks provided deeper insight into opportunities how to deal with the circumstances of the desiderata of an interdisciplinary computer science. In a formidable way the Joint Workshop demonstrated that coming events and analysis shall not be limited to “a review of the actual position of the discussion” of research in computer science, but also might have to address the self-commitment that could be a common vanishing point.
